see that is were it is a #$%@^ cause i have a vertex IN-180 and a SRO1000sss for skimmers but i would need more lights then just my IT-2060 i would need two more lights and that is $$$ i could get a couple WP-40s not that expensive but lighting would be the biggest #$%@^ the 4Ft 120 gallon would be my best bet with the equipment i have but a 180 is soooooooo tempting
